1 Claim.

My present invention relates to improvements in furniture, andparticularly to such oce furniture as desks and the like having aplurality of supporting legs and a work top; and the primary objects ofimprovement are, first, to provide a convenient means for changing theheight of such furniture as desks and the like; second, to provide adesk or like piece of Yfurniture that can be easily adjusted inheightfor the accommodation of users of kdifferent stature and weight;third, to provide a simple means of changing the height of desks andlike furniture; fourth, to provide an improved means for changing theheight of desks and like furniture that will be simple in construction;fifth, to provide an improved means for changing the height of desks andlike furniture that will be readily understood by the usual layman;sixth, to provide an improved means for changing the height of desks andother furniture that will be strong and not liable to disorder. Thesenamed objects and such other objects as may appear from a perusal of thefollowing description when said description is taken in connection withthe structure disclosed in the accompanying drawing, in which- Figure 1is a perspective view of an oice desk provided with my improved meansfor changing the height thereof.

Figure 2 is an enlarged vertical elevation View of one of the desktubular supporting legs adjusted to its short length for supporting thedesk at its lower height, with the extended desk leg shown by brokenlines.

Figure 3 is a side elevation view of one of the leg extension members.

Figure 4 is a vertical cross-section View showing the elementscomprising my present invention in assembly and taken on a. planeextending vertically on line V-V of Figure 5, the vView showing a deskleg extended as when the desk is raised.

Figure 5 is a cross-sectional view of the desk leg shown in Figure 3 andtaken on a plane looking downward from line X-X of Figures 2 and 4.

Throughout the drawing of my invention, similar numerals refer tosimilar parts or portions, and referring thereto- Numeral I, designatesthe top of a desk having my improved means for changing its height, 2the legs by which the desk is supported, 3 side drawers of the desk, 4,the knee space between the drawers 3 and below the master drawer 5.Numerals 6 designate the hollow foot or slide shoe tubular desksupporting legs 2 by springable metal dowel members when the desk is inlowered position. Numeral 'I designates the tubular extension members bywhich the height of the desk is changed, the said extension membershaving extending around their top bead 8 whereby the l walls of theextension member is strengthened and stiifened, each extension memberhaving lower end, springable dowel members 9 preferably formed asintegral parts of the side walls of the tubular extension members, eachdowel member having an inturned ange Iii at its free end in spaced apartrelation to the tubular body portion of the extension member. Eachsupporting leg of the desk having springable metal dowel members IIextending from its end and with indesk leg or the foot member is forcedover the dowel members of the extension member. Within the tubular leg 2and extending longitudinally thereof is reinforcing member I4 consistingof a strip of sheet metal of L cross-sectional form and overlapping aseam extending longitudinally of theleg at one of its vertical cornersand secured to the inner side of the side walls thereof by spot welding.

The usual height of office desks and other like office furniture isthirty inches, this height is satisfactory for persons of normalstature, but not for persons of short stature, persons having short legsor overweight. For these latter persons, the chair seat occupied must beelevated to accommodate for reach over the top of the desk top, and theperson is short legged or of considerable overweight the edge of thechair seat chafes the under-side of the leg thereby retarding bloodcirculation, and causes nervousness, or cramps, all of which is annoyingand detrimental to health, and efficiency of the worker -at the desk. Mypresent invention overcomes all of these named objections, as the deskor other furniture may be changed in height to a height best suited tothe person using the desk, the amount of elevation provided in the deskshown is one and one half inches, but can be any amount desired bymerely providing suitable length extension members.

Having described my present invention, the

rights to which I desire to secure are disclosed in the claim.

I claim:

In a desk having a Work top adapted to be raised and having a pluralityof supporting legs each leg having a pair of springable dowel meinbersin vertically spaced apart relation to each other extending from itslower end 4and a hollow foot member adapted tobe detahably secured tothe supporting leg by the saiddow'ermembers for adjusting the leg lengthand thereby raising the y work top of the desk, a. hollow extensionmember having a' cross-sectional form corresponding generally to thecross-sectional form of the said leg and adapted to be engaged by thedowel members extending from the said leg, the said extension memberhaving a plurality of springable dowel members extending from the lowerend thereof forkengaging said hollow foot substantial- -ly fasdescribed.
